Embodiment 1

[0043] Such as figure 1 As shown, the tobacco hydroponic module of the present embodiment includes a hydroponic frame 1, a three-layer planting tank 2 arranged on the hydroponic frame 1, two spliced ​​planting boards 3 arranged on the planting tank 2 and a Each layer of planting groove 2 liquid inlet 5 and liquid outlet 6 connected nutrient solution barrels, the planting plate 2 is wider than the planting groove 1cm around, and covers the opening of the planting groove, and each planting plate is provided with 12 planting holes. Nutrient solution is housed in the planting tank 2, and the tobacco seedlings can be fixed on the planting holes 4 in the existing manner, and the roots of the tobacco seedlings pass through the planting holes 4 to contact the nutrient solution, and the nutrient solution barrels are connected to the liquid inlets of the planting tanks of each layer. The connected pipeline is provided with a pump, and the liquid outlet of the adjacent planting tank is ...

Embodiment 2

[0067] In the tobacco cultivation method based on the light environment in the plant factory of this embodiment, the spectral energy distribution of the light in step (2) is as follows: the number of photons with a wavelength of 380-399nm is 0.8%, and the number of photons with a wavelength of 400-499nm is 30.2 %, the number of photons with a wavelength of 500-599nm is 49%, the number of photons with a wavelength of 600-699nm is 19%, and the number of photons with a wavelength of 700-780nm is 1%.

[0068] In step (3), the nutrient solution is changed every 2 weeks.

[0069] The cultivation temperature of the tobacco hydroponic module is 26°C, the humidity is 65%, and the concentration of carbon dioxide in the air is 400ppm.

[0070] All the other are identical with embodiment 1.

Embodiment 3

[0072] In the tobacco cultivation method based on the light environment in the plant factory of this embodiment, the spectral energy distribution of the light in step (2) is as follows: the number of photons with a wavelength of 380-399nm is 0.1%, and the number of photons with a wavelength of 400-499nm is 37 %, the number of photons with a wavelength of 500-599nm is 36.4%, the number of photons with a wavelength of 600-699nm is 20%, and the number of photons with a wavelength of 700-780nm is 7%.

[0073] In step (3), the nutrient solution is changed every 10 days.

[0074] The cultivation temperature of the tobacco hydroponic module is 28°C, the humidity is 70%, and the concentration of carbon dioxide in the air is 500ppm.

[0075] All the other are identical with embodiment 1.

[0076] As a control, we simultaneously irradiated with a philips-T5 fluorescent lamp, and the rest were the same as in Example 1. The specific test comparison results are shown in Table 1:

Abstract

The invention relates to a tobacco cultivation method based on the light environment. The method comprises the following steps of step (1), disinfection of tobacco seeds; step (2), tobacco seed culture; step (3), transplanting; step (4), dark period culture; step (5), lighting treatment; step (6), nutrient solution adjustment; step (7), topping and branch removing. Compared with traditional fluorescent lamp spectrum, the method increases the yield of tobacco leaves by at least 35% when other growth conditions are maintained and the light intensity is the same. The method covers the whole process of the tobacco leaves from planting to harvesting in a plant factory, the whole process is carried out indoors, the tobacco leaves are completely unaffected by the external environment, and continuous production can be achieved throughout the year. The method can make tobacco plants thrive and develop rapidly, and the root system is sound and developed.

Description

technical field [0001] The invention relates to a tobacco cultivation method, in particular to a light environment-based tobacco cultivation method, and belongs to the field of tobacco cultivation. Background technique [0002] tobacco( Nicotiana tabacum ) for Solanaceae (Solanaceae) Nicotiana (Nicotiana) Annual or perennial economically important crops. Tobacco is a light-loving plant, but tobacco planting in my country is seriously affected by the external environment, and there are problems of insufficient light intensity and insufficient light time. Especially in the nursery stage, the cultivation of tobacco seedlings in the current flue-cured tobacco production mainly implements centralized seedling cultivation in solar greenhouses. Plastic films and other heat preservation measures make the sunlight in the greenhouses seriously insufficient in originally cloudy and rainy weather. As a result, the growth of tobacco seedlings is retarded, the seedling period become...
